RIBBON-FASTENING MACHINE.

Specification of'Letters Patent.

Patented May 14, 1907.

To all whom it may concern:

Be it known that we, ALEXANDER MONT- GOMERYMAGEE andWILEREDNORMANEARLE, both subjects of the King of Great Britain, and residents of St. John, in the Province of New by side portions 10 and 11 bent to an angle of approximately 120 to each other, and the portions 10 carry two opposite trunnions 12 and 13.

The device operates as follows: The clamp Brunswick and Dominion of Canada, have and tension bar are assembled as shown in invented a new and Improved Ribbon-Fastening Machine, of which the following is a full, clear, and exact description.

Our invention relates to improvements in ribbon roll securing devices, and comprises a clamp having a tension bar pivoted thereon in a manner hereinafter more fully described.

The objects of our invention, are, first, to provide a more perfect fastener for ribbons contained in roll than is now known, and secondly, a fastener that will readily permit of the unrolling of the ribbon when desired.

Reference is to be had to the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a perspective view of a roll of ribbon showing our device applied thereto; Fig. 2 illustrates a portion of a roll of ribbon and shows our device applied thereto, the device being in section; Fig. 3 is a perspective view of our device complete; and Fig. 4 is a perspective view of the tension bar.

In the drawings 1 is the roll of ribbon or similar material. a

2 is the clamp having legs 3 and 4 bent at right angles to the back portion 5 thereof. The length of the back portion 5 will ordinarily be substantially equal to the width of the roll of ribbon to which the device is to be applied, although it is not necessary that it be of any definite dimensions so long as it is long enough to permit the legs 3 and 4 to engage the sides of the roll. In the leg 3 is a hole 6 and in the leg 4; is a slot 7, respectively adapted to receive trunnions 12 and 13 pro jecting from the sides of the tension. bar. The tension bar consists preferably of a continuous wire bent into the shape clearly shown in the drawing, and consists of two portions 8 and 9 passing parallel with the back 5 of the clamp 2 across the roll. The 9 are connected Fig. 3. The parts are then slipped over the edge of the roll as shown in Figs. 1 and 2, the loose end of the roll being passed under 9 and over 8, thence backward over 5 and again under 9 and forward. It will now be seen that while the parts remain in this position, with 8 bearing upon the roll, it will be impossible for the ribbon to unroll or be unrolled, because any pulling upon the loose end of the ribbon will hold the portion-8 of the tension bar and back portion 5 of the clamp tightly against the roll and prevent the turning of the same. If, however, the clamp be raised by the hand, slightly, so that the portions 5, 8 and 9 are no longer in actual contact with the roll this fastening action cannot occur and the ribbon can be freely unwound.

All parts of the invention may be made of brass or other suitable material and of different sizes to suit varying widths of ribbon as stated.

We desire that our claims cover such modifications of our device as fall fairly within the scope of our invention.

Having thus described our invention, we claim' as new and desire to secure by Letters Patent 1. In a ribbon roll fastener, a clam adapted to straddle the roll, and a tensionIar pivoted on said clamp, said tension bar having side members adapted to embrace the sides of the roll, and two s aced portions extending across the width ofthe said roll.

2. In a ribbon fastener, a clamp having legs bent at right angles to and on the same sides of the back thereof, one of the legs being provided with a hole, and the other l with a slot, and a tension bar having two members extending parallel to said back, said members being connected at their ends by side pieces bent to a desired angle, said pieces having trunnions projecting therefrom adapted to take bearings in said hole and slot l respectively. W

3. Aribbon fastener, comprising asubstannames to this specification in the presence 0 tially U-shaped body portion adapted to two subscribing witnesses. straddle a roll, and a tension bar pivoted between the pp lnembers of the y and ALEXANDER llIONTGOMEItY MAGllll.

b i w p v u v w 5 having two parallel and spaced members con- LAMA" nected by angular side members adapted to Witnesses: embrace the sides of a roll. WM. BRODIE,
